DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

DNA analysis is crucial for identifying individuals and their relatives, using technologies like PCR, electrophoresis, and ...

DNA is genetic material found in the cell nucleus, carrying inherited information (genes) that give us our unique characteristics. Each one of our 100 million million cells contains nearly two ...

Scientists have finally captured footage of the microscopic machinery that allows our cells to copy DNA—a fundamental process ...

The Pol-theta enzyme (blue) joins two parts of a broken DNA strand (yellow). This process is mutagenic and can give rise to cancer. LA JOLLA, CA—DNA repair proteins act like the body’s editors ...

Messenger RNA (mRNA) is a subtype of RNA. An mRNA molecule carries a portion of the DNA code to other parts of the cell for processing. mRNA is created during transcription. During the ...

Although previous studies have mapped parts of Pol-theta's structure, the enzyme's interactions with DNA weren't well understood. "What's been missing is how Pol-theta actually engages DNA ...
